Biography
Klementia was born in 851 to a lowborn family of Catholic Germans in East Frisia (present-day Lower Saxony, Germany). Klementia became a noble when she married Hrodulfr of Ostfriesland, a Norse raider who launched several attacks on East Francia and the former Carolingian Empire's other states for loot.
